@me1958424 I’ve been using Blender for half a year now and I never knew this, what is life…?
In all seriousness thanks to everyone who posted! I ended up tinkering with the node editor some more, finally realizing that “clip” exists on the image texture node and went from there. It was still a little funky but I got a result I was happy with.
So thanks @williamatics for first pointing me in the right direction and reassuring my questions, thanks @carrotnl for bringing the min/max to my attention and showing your cool model, thanks @baukepost for giving me quite a bit of insight into texture painting, I’ll be sure to experiment with that more, and thanks @me1958424 for showing me a vital button “hidden” in plain sight which changed my project around, appreciate you all!
EDIT: Wow, the @ button is screwed.
